Summary The development of urbanization and industrialization has improved the comfort level and the quality of human’s life effectively. But at the same time, it also caused many global environment problems, such as air pollution, greenhouse effect and urban heat island (UHI). The environment cannot keep the balance because of lots of industrial activities, anthropogenic heat and building surface effect. Almost 3 billion people, who are living in cities, have to face this situation, and the quantity is still increasing. The authors use literature research methodology, case study, comparative study and trend analysis study while writing. UHI have a harmful effect (such like photochemical smog and increasing energy use) on urban ecological environment, daily life and health. As the product of urbanization and industrialization, UHI has become one of the most important climate issues. Urban green space is helpful to reduce urban heat islands. London has a better urban green space system to face UHI and Hong Kong still has a long way to improve the green environment for reduce UHI. This article consider that roof greening is a suitable method to help Hong Kong gets rid of urban heat islands. And the lighting and population could indicate the level of urbanization, also can reflect the effect of urban heat islands preliminary. Over-capitalized lighting will exacerbate urban heat islands.
